POstgreSQL Tablespace deletion issue

HI,

I am using PostgreSQL 8.4 in windows XP. Also using Slony-I for
implementing master/slave support. I have a data base with some tables
and a table space with some other tables in another location. My issue
is that after a 30 days continuous run, some of the files in the
PostgreSQL table space get deleted. The modification that I had made
recently is that, I have created indexes on some of the tables in the
table space. But the indexes are actually created on the default table
space, not in the table space where the tables resides. Is any problem
in it? Note that there is antivirus or clan up applications running on
the system. The only thing that we have done is that , the machine has
restarted 5 - 6 times without stopping the PostgreSQL server. (The
PostgreSQL server running on 5432 post is a custom database server
created and not the default PostgreSQL server coming when PostgreSQL is
installed.) Is there any chances for failing the crash recovery? Is
there any chance for deleting the table space files, if the crash
recovery is failed ? How can we avoid this ?

Thanks & Regards,

Vishnu S
